  • the present invention is widely applicable to the inspection of rod-like articles for smoking by the inspection method described below, which is not limited to the presence or absence of the use of.
  • FIG. 12 is a flowchart showing the procedure of the inspection method.
  • a plurality of lights having different wavelength distributions, that is, different colors are generated (light generation step).
  • the inspection light Li is formed from a plurality of lights (adjustment step).
  • a color tone process is performed in which the color of the inspection light Li is adjusted by mixing the lights generated in the light generation process.
  • the inspection light Li is irradiated to the rod-like article (irradiation step).
  • the irradiated inspection light Li receives the measurement light Lm obtained by acting on the rod-like article (light receiving step).
  • the quality of the rod-like article is determined based on the measurement light Lm (determination step), and the inspection procedure is ended.
  • the rod-shaped articles determined to be defective in the main inspection are appropriately excluded.
  • the color of the inspection light Li is adjusted by adjusting the intensity of each light generated in the light generation process.
  • the inspection light Li is adjusted to the color that can distinguish the boundary B of each segment, so that the disposition of each segment can be easily made good. It can be determined.
  • the influence of the capsule C on the measurement light Lm can be reduced by adjusting the inspection light Li to the same color as the object. Since the boundary B of each segment can be clearly identified and the type of each segment can also be identified, the inspection accuracy of the rod-like article can be further enhanced.
